JSF :: Data Table Showing Records In Columns?

Aug 2, 2014

I'm new in JSF, so maybe this is a very simple problem:

My small application uses 'primefaces ' and I'd like to display the course of some laboratory values this way:

Parameter2014-08-022014-08-012014-07-31
Natrium [mmol/l]140.0135.0135.5
Calcium [mmol/l]2.12.02.3
Kalium [mmol/l]4.34.05.3
[...] [mmol/l]1.32.02.3

Data is stored in a per day manner, so each table column shows one record.

In JSF, I've only seen tables showing records in rows. How to display a transposed data table in JSF.

Runnable Jar Does Not Show Data From Database

Mar 13, 2014

I am still working on my java course and now we have to create a jar file from a previous project (this is a project where a connection to the database is made and data is shown in a frame).

When I follow the instruction in my course material I don't get it to work. I've tried the following:

1. Open eclipse on windows xp
2. Right click on the project folder in eclipse
3. Click on "export" in the menu that appears
4. Choose "runnable jar"
5. click next
6. I insert the following parameters:

- Launch configuration --> I select my main class
- export destination --> I select the folder D:
- library handling --> Package required libraries into generated jar

7. click Finish

This is what happens when I dbl click the jarfile (wampserver is running):

1. I get an error: "SQL ERROR: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server."

2. I click ok on the message and the following message appears: "SQL Error: null"

3. I click ok on this message and the frame with the fields appears without data from the database.

This is a crosspost to: [URL] ...

Servlets :: Insert Data To Database?

Aug 2, 2014

How can we insert data through java servlet?

I can insert data to table by using JSP Scriptlet easily but I have a hard time with servlet.

public class UsertToDatabase() {
public boolean inserUser(String name, String email, String pwd) throws SQLException {
PreparedStatement pstmt = null;
boolean flag = false;
System.out.println("start");
openConn();
System.out.println("start_1");
if(conn == null) {

[code]....

I am positive that the above code function fine. The problem is whenever I call UserToDB() class inside the servlet, and I got this error: java.lang.ClassNotFoundException: org.postgresql.

Driver which mean that my conn (connection) is not connected to the database but I have ensure to do so by calling openConn() before start the transaction.

This is my servlet code:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String username = request.getParameter("username");
String email = request.getParameter("email");
String password = request.getParameter("password");
List<String> errList = new ArrayList<String>();

Retrieve Data From Database By Joining Tables

Dec 23, 2014

I am trying to retrieve data from my database by joining my tables. So far i have managed to join my four tables in my database and retrieve all the information in that table. Now what i want to do is create a prepared statement in java that allows me to retreive certain data. Here is my joining query.

SELECT student.idNumber,student.names, student.surname,
course.description,
coursemarks.mark,
class.form,class.id
FROM `student`
LEFT JOIN `coursemarks` on student.idNumber = coursemarks.studentid
LEFT JOIN `course` on course.courseid = coursemarks.courseid
LEFT JOIN `class`on student.idNumber = class.studentID;

What I want is to select all the data depending on the class passed and the form passed, e.g a person might decide to select a certain form only or a certain form and class

Creating Table Model For Data From Database

Sep 9, 2014

I'd like to create my own Table Model to handle data from an SQLite database using JSwing, but I'm having difficulty. How to confirm the following:

-- A table model is an object that contains methods for manipulating data in the table, right?

If that's the case, then how should I create a Table Model to handle data coming from a database. From what I understand...

My custom Table Model needs to subclass AbstractTableModelI then override 3 methods from AbstractTableModel (getRowCount(), getColumnCount(), getValueAt())

As it relates to drawing data from a database, how should I be thinking about this problem (i.e. creating a Table Model that can work with a database)?
